Connect to Cvent Data from PowerBuilder

The CData JDBC Driver for Cvent is a standards-based control that can be used from any platform or development technology that supports JDBC, including PowerBuilder. This article shows how to use the CData JDBC Driver for Cvent in PowerBuilder.

This article shows how to create a basic PowerBuilder application that uses the CData JDBC Driver for Cvent to perform reads and writes.

Connect to Cvent Data from PowerBuilder

Follow the steps below to use the Database Painter tool to create a database profile based on an JDBC URL for Cvent. You can use a database profile to save connection properties. In the Database Painter, you can graphically manipulate data as well as execute SQL queries.

1. Add the driver JAR to the PowerBuilder classpath. Set the CLASSPATH system environment variable to the path to the driver JAR, located in the lib subfolder of the installation directory.

   Note: If you are using PowerBuilder Classic, you can also add the path to the driver JAR by clicking Tools -> System Options -> Java.

2. Click Tools -> Database Painter.
3. Right-click the JDBC node and click New Profile.
4. In the Database Profile Setup dialog, enter the following:
   • Profile Name: Enter a user-friendly name for the profile.
   • Driver Name: Enter the class name of the driver, cdata.jdbc.cvent.CventDriver
   • URL: Enter the JDBC URL.

     Before you can authenticate to Cvent, you must create a workspace and an OAuth application.

     Creating a Workspace

     To create a workspace:

     1. Sign into Cvent and navigate to App Switcher (the blue button in the upper right corner of the page) >> Admin.
     2. In the Admin menu, navigate to Integrations >> REST API.
     3. A new tab launches for Developer Management. Click on Manage API Access in the new tab.
     4. Create a Workspace and name it. Select the scopes you would like your developers to have access to. Scopes control what data domains the developer can access.
        • Choose All to allow developers to choose any scope, and any future scopes added to the REST API.
        • Choose Custom to limit the scopes developers can choose for their OAuth apps to selected scopes. To access all tables exposed by the driver, you need to set the following scopes:

          event/attendees:read	event/attendees:write	event/contacts:read
          event/contacts:write	event/custom-fields:read	event/custom-fields:write
          event/events:read	event/events:write	event/sessions:delete
          event/sessions:read	event/sessions:write	event/speakers:delete
          event/speakers:read	event/speakers:write	budget/budget-items:read
          budget/budget-items:write	exhibitor/exhibitors:read	exhibitor/exhibitors:write
          survey/surveys:read	survey/surveys:write

     Creating an OAuth Application

     After you have set up a Workspace and invited them, developers can sign up and create a custom OAuth app. See the Creating a Custom OAuth Application section in the Help documentation for more information.

     Connecting to Cvent

     After creating an OAuth application, set the following connection properties to connect to Cvent:

     • InitiateOAuth: GETANDREFRESH. Used to automatically get and refresh the OAuthAccessToken.
     • OAuthClientId: The Client ID associated with the OAuth application. You can find this on the Applications page in the Cvent Developer Portal.
     • OAuthClientSecret: The Client secret associated with the OAuth application. You can find this on the Applications page in the Cvent Developer Portal.

     Built-in Connection String Designer

     For assistance in constructing the JDBC URL, use the connection string designer built into the Cvent JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

     java -jar cdata.jdbc.cvent.jar

     Fill in the connection properties and copy the connection string to the clipboard. A typical JDBC URL is below:

     jdbc:cvent:OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;InitiateOAuth=GETANDREFRESH
5. To view and modify a table, right-click a table and then click Edit Data -> Grid.

Using Cvent Data with PowerBuilder Controls

You can use standard PowerBuilder objects to connect to JDBC data sources and execute queries. The following example shows how to retrieve Cvent data into a DataWindow. You can add the following code to the open method:
